Goldfish are one of the most beloved pets in the world, yet when it comes to their care, myths and misinformation swirl around like autumn leaves in the wind. If you’ve ever felt confused about the best way of keeping goldfish, you’re certainly not alone! Let’s dive deep together, clear the waters, and learn how to care for these shimmering beauties the right way.
Whether you’re a beginner or just curious, understanding the best way of keeping goldfish is essential—not only for their health but for your peace of mind too. Plus, we’ll sprinkle in some surprising myth-busting along the way!
Understanding Goldfish: More Than Just “Starter Pets”
Many people think of goldfish as low-maintenance starter pets, almost like a practice run before getting “real” pets. Honestly? That couldn’t be further from the truth!
- Gold fish are intelligent creatures that can recognize their owners.
- They live long lives, often over 10–15 years when cared for properly.
- They need ample space to thrive, contrary to the tiny bowls often marketed for them.
Imagine adopting a playful puppy and keeping it locked in a closet. Shocking, right? Yet that’s often what happens when goldfish are kept in cramped bowls.
Common Myth #1: Gold fish Can Live in Bowls
You’ve seen it in movies and cartoons—the classic goldfish in a tiny glass bowl. It’s a cute image, but sadly, it’s one of the most damaging myths.
Here’s the reality:
- Gold fish produce a huge amount of waste.
- Bowls quickly accumulate toxins like ammonia, which can be deadly.
- Lack of space stunts their growth and harms their organs.
Pro Tip: Instead of a bowl, aim for at least a 20-gallon tank for a single goldfish. Want more than one? Add an extra 10 gallons per fish.

Common Myth #2: Gold fish Stay Small If Kept in Small Tanks
This one’s a real heartbreaker. Some believe that gold fish “adapt” their size based on their tank. While it’s true their growth may be stunted in small spaces, it’s not healthy—it’s tragic.
- Internal organs keep growing, leading to deformities.
- Lifespan is drastically shortened.
- Health issues like swim bladder disease become common.
Better Approach: Provide the largest tank you can manage. We should remember that, a healthy and matured gold fish can grow up to 12 inches or more!

Common Myth #3: Gold fish Don’t Need Filters
Some people think gold fish are so hardy that filtration is optional. Spoiler alert: it’s not!
- Gold fish generate 3–4 times more waste than tropical fish.
- Without a filter, toxic ammonia levels spike rapidly.
- Poor water quality leads to stress, disease, and early death.
Key Tip: We should choose a filter or filtration system double of your tank size. For example, filter suitable for 60 gallons should be used to 30 gallon tank.

Common Myth #4: Goldfish Eat Only Flakes
Flakes are handy, but they’re just the tip of the iceberg when it comes to goldfish nutrition!
- Goldfish are omnivores in nature, live on a mix of animal and plants.
- Nutritional deficiencies can be found if relying only on flakes.
Better feeding plan:
- High-quality pellets (more stable nutrition than flakes)
- Blanched veggies like peas, spinach, and zucchini
- Occasional treats like bloodworms or brine shrimp
Feeding your gold fish right is just like ensuring a child gets veggies alongside their pizza! You can explore more feeding tips at Feeding Your Betta: The Ideal Diet for Health and Longevity.
Common Myth #5: Goldfish Are Coldwater Fish Only
While it’s true that gold fish prefer cooler temperatures compared to tropical fish, they still have a preferred temperature range.
- Ideal temperature: 68°F to 74°F (20°C to 23°C)
- Too cold? Their metabolism slows, leading to illness.
- Too hot? Oxygen levels drop, causing stress.
Pro Tip: Use a reliable thermometer and maintain consistency. If you live in extreme climates, a heater or chiller might even be necessary!
